National Loop Co. 22' (4' X 7') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 11' Wide Driveways - K-NL11-14

Designed to be paved over, the National Loop Co. 22' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a preformed 14 AWG inductive loop for new-surface installations. Connected to a loop detector, it reports every vehicle that crosses the sensing area, giving the gate operator the non-contact detection that fills one of the two UL 325 entrapment protection slots. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. Its 7' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to slightly wider suburban single-car drives and older neighborhoods with wider lot cuts.

Features:

• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
• Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
• Predetermined number of turns removes the guesswork of achieving optimal read range
